This app is a great studying resource when prepping to take your CDL permit test. Before downloading it I looked at the reviews and one said to study it like it’s your bible! And that’s so true!! I read through the manual before finding this app, but I think that this allowed me to recall and really understand what I read. It’s awesome how it has a “see why” option when you miss a question. This allows you to look back at your manual and read about it. I took my general knowledge, combination and air brake tests out of Indiana. The GK test is about 90% similar to the questions they have on here. I passed and only missed a few on my first try. For the combination test, it’s about 95% similar to the questions on here. I passed on first try. I still have yet to take the air brakes but I will update after. Thanks!

The question about driving through water in the doubles/triples test is wrong. The explanation is correct, but if you answer according to the explanation you’re marked as incorrect.
